Your maps and preferences may be different than those of the person you received them from, so to be sure you ride the intended route. You must ensure the following.

Map Version & Settings:

- You don't need the latest routes, but it's wise to ensure the map version in YOUR device is the same as the version in YOUR BaseCamp. - In YOUR BaseCamp AND device, turn off all Avoidances & select Fastest Time

To ensure the Routes are as intended:

- Open the GDB or GPX file in your software, then make duplicates of each route (usually a right click will show the option).- Change the color of the Duplicate route (usually double click, then go to &#147;Info&#148; and look there)- Note the mileage- Then Re-calculate the Original route. - The mileage should stay the same.- If the route mileage is different, look for the color you changed the Duplicate route to. You will need to add a Waypoint or Via point to the Original route to make it match the Duplicate route. - Once the two routes are the same, delete the Duplicate route, then load the Original route onto your GPS.
